Imagination Machine

This strange hybrid computer came in two parts: a videogame console and a computer. The game system, called the APF MP-1000, was released in 1978. It had two controlers, each with a joystick and a numeric keypad. It came with a built-in game called "Rocket Patrol".

The computer console, the "Imagination Machine" was sold as an add-on for the MP-1000. You could also buy both at the same time (most people did). The computer has a 53-key standard typewriter keyboard, a built-in stereo cassette deck (1500 baud), a built-in sound-speaker and an internal operating system and BASIC language interpreter. The APF BASIC, delivered on cartridge, was quite poor. You had to use a lot of POKEs and CALLs to play with graphics. For example, to clear the screen, the command was CALL 17046.

The video game system nestled on top of the keyboard module. This computer add-on concept would later be used by several game system manufacturers like Coleco with their Colecovision game system connected to the Adam Computer, or Intellivision and their ECS module (and keyboard component).

We need more info about this computer ! If you designed, used, or have more info about this system, please send us pictures or anything you might find useful.
Please consider donating your old computer / videogame system to or one of our partners from anywhere in the world (Europe, America, Asia, etc.).


The stereo tape recorder was supposed to allow you to record voice audio into a second track while you saved a program. But the computer recorded data into both tracks if you didn''t plug-in a microphone, so most tapes just had (loud) data noises unless you turned down the volume. The built-in speaker *only* played audio from the tape drive. All computer music and sound fx came through the television.

I went through five of these that were defective in various ways before I gave up and got my money back. The version of Basic was abysmally slow, and it did not have things like trig functions.

The specs looked great and it looked like the complete package, but it just didn''t deliver on its promises.
